Stressed:
Hiro looked over the designs for his robot again, knocking something that wasn't important to the ground. The final presentations for this semester were coming up, and Hiro by no means felt prepared. The genius was fiddling with wires when Fred found him. It was three in the morning, and Fred smiled to himself a little.
Tadashi had mentioned that Hiro had a bit of an obsessive personality.
"Hiro, it's time for you to get some sleep," Fred said, grabbing Hiro by the hoodie. Hiro literally hissed and Fred, which made the older chuckle.
"You're not going to scare me off. You really need some sleep, kiddo, come on," Fred insisted, pulling Hiro away from his work. Hiro whined and complained, but let Fred drive him home and drop him off to a very tired (and worried) Aunt Cass.
Fred stayed the night at the Hamada's place, making Aunt Cass tea and making her go to bed before having Hiro lay down on the couch, his head on Fred's lap. Hiro almost cried when he saw what Fred was doing – he was replicating the environment that Tadashi often provided when he was still alive.
"Fred, you don't have to do this," Hiro croaked. He was finally admitting to himself that he was extremely tired.
"I know," Fred replied casually, gently caressing Hiro's hair. Hiro sighed at the comforting gesture. "I feel like, after all you've done for me, it's the least I could do, Hiro."
"Hmm?" Hiro questioned.
"Just sleep," came the soft reply.
Hiro obliged.
